#### Formula:

Total Surface Area of Cuboid = 2 x ((Length x width) + (Width x Height) + (Length x Height))

#### Example

**Let us consider a cuboid with length as 9 cm, width as 5 cm and height as 3 cm respectively.**

Total Surface Area of a Cuboid (TSA) = 2 x ((Length x width) + (Width x Height) + (Length x Height))

= 2 x ((9 x 5) + (5 x 3) + (9 x 3))

= 2 x 87

= 174

Therefore, TSA value is 174 cm ^{2}
